d To all whom t may concern Be it known that I, CONRAD SCHROEDER,` a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented new and useful Improvements in Bottle-Filling De`- vices, of which the following is a full, clear,` concise, and exact description, reference being had to the accompanying drawing, forming a part of this specification.

My invention relates to bottle filling devices.

In bottling beer, and other beverages, it is usually desirable to expel all the air from the bottle before it is sealed so "as to prevent oxidation and precipitation of albuminoids, and other deleterious effects. T o accomplish this end, the carbon dioxid gas, which is evidenced by the foam, is permitted to rise to the top of the bottle and drive out the air. While this condition prevails, the seal is applied, and, hence, air is excluded from the bottle. The same method is employed in canning vegetables andthe like. tables are hot and vapor and steam are arising therefrom and expelling the air. `Accordingly the cans are sealed without air therein. d

Automatic machines are generally used in bottling beer and other beverages containing carbon dioxid gas. One machine is e1nployed to lill the bottles and another to seal them. It is important that the filling machine operates in such a manner as to reduce the rise of foam and the consequent loss of carbon dioxid gas to a minimum during the act of filling the bottle. Different types of filling machines operate differently and have different adjustments. In bottles filled by some types of' machines, the gas usually rises to the top, while in those'lled by other types of machines, the gas frequently fails to rise to the top.

In order to insure the rise or' foam and gas sufficiently to expel all the air before the seal is applied, I have devised an improved device, by means of which a small quantity of the beverage, or other suitable fluid, may

be injected into the bottle after it has been filled in the usual manner. I thereby stimulate the rise of foam and gas sulliciently to insure its reaching the top of the bottle. My device may be operated by an attendant who receives the bottles after they have been The cans are sealed while the vege-l filled, or it be attached to one of the machines and `operated automatically.

In the accompanying drawings I i have.v illustrated devices which I have worked out in practice `to attain the objects of my invention. It will, of course, be understood that my invention may be embodied in other forms which will'be within the purview of the claims forming a partof this specifica tion. l

The figures in the drawings are as follows: I d 1 Figure 1 is a side elevationl of one of my devices applied to a bottle; Fig. 2 is a vertical section taken through the device shown in Fig.`l; Fig.` 3 is a detail sectional view of one form of valve that I use, `the valve being open; and Fig. 4c isa sectional view through another form of my invention.

I shall first describe the device shown'in Figs. l, 2 and 3. I providea casingV l, which may be made in such form that it may be held by the hand. The casing which I have shown consists of a cylindrical tube to which is threaded a top 2 and abottom 3; A tube :i ,4 is preferably threaded into the casing and forms'an inlet port 5. To this tube is ati-1 tacheda lexible tube 6 which is connected to a source of suitable fluid. The fluid is usually the beverage which is being bottled. Of course, carbon dioxid gas, or any other suitable fluid, may be used. 'The bottoni i5 is preferably provided with a spout 7 adapted to extend a short distance into the neck'. of the bottle. Applied to the' lower end of the 'casing is a resilient washer 8 made of'rubber or other suitable material, adapted to bear against the top of the bottle when the-device is placed in' position for op# eration. An outward flaring flange or bell 9 is attached to the lower end of the casing to centerthe device when it is applied to the bottle. This flange or bell serves tohold the washer 8 in position and is preferably fastened to the bottom 3 by means of a screw 10. Extending upwardly from the bottom 3 inside of the casingis a post ll over which fits a valve 12 carried by a rod l2a extending upwardly through the top 2. rlhe valve 12 is free to slide vertically on the post Il. Through the bottom of the casing extends a passage, forming an outlet port, 13. This passage commences at the side of the post 11 and then turns and runs down through the bottom to the spout 7 The outlet is preferably restricted so that ya fine stream may be ejected therefrom. Of course, the outlet port need not be restricted throughout its entire length as the desired end may be obtained by simply restricting the port at the spout. The valve 12 normally closes the outlet port 13 and is provided with an aperture 14, Which registers With said port when the valve is pushed down. The valve rod 12a is preferably surrounded by a cap 15 which is threaded to the top 2 and contains a packing 16. A

finger lpiece 0r button 17 is preferably mounted on the upper end of the valve rod. The valve is normally pushed upwardly by means of ysprings 18 so as to close the valve. These springs surround guide rods 19 threaded'into the bottom,l 3. A cross piece 20 mounted on the valve rod 12 bears upon the springs and isprovided with holes at its ends through which the guide rods pass. Screws 21`are'threaded into the tops of the guide rods to form stopsfor the cross piece.

When the device is inpuse, beer or other fluid enters the casing under pressure through port 5. After a bottle is filled, the device is applied thereto and the valve opened momentarily, thereby sending a fine stream of beer or other suitable fluid upon the" surface of the beverage and causing gas and foam to rise sufficiently to expel the air from the bottle.v The bottle is then ready to be sealed.

Another form of my invention is illustrated in Fig. 4. It consists of a casing 22, containing a valve 23 resting on a seat 24. The valve is mounted on a stem 25, which pasSeSthrough the side 0f the casing and moves horizontally. The outer end of the stemissurrounded by a cap 26 threaded to the;casing,l said cap, holding in position a Washer 27 Which retains a packing 28 surrounding the valve stem. The valve is normally pressed against the seat by means of a spring Q9, one end of which bears against Vthe-valve and the other end against the inside, of a cap 30 threaded to the case.

Many variations may be made in the detail features of the construction which 1 havel hereiny described, Without in any Way departing from my invention.

ther parts. of thisy structure are similar to thosevshown in Figs. 1, 2 and 3. The valve is opened by pressing the valve stem inwardly. l i

Having thus described my invention, What I desire to secure by Letters Patent is:

1. A device of the character described including a casing having an inlet port connected to a source of suitable fluid and a restricted outlet port, a post extending into said casing and having an opening communicating With said outlet port, a valve movable upon said post, resilient means for normally closing said valve, and means for op erating said valve extending through said casing.

2. A device of the character described, comprising a casing having an outlet port in the bottom thereof and a suitable inlet port connected to a source of suitable fluid, a post extending upwardly from the bottom of said casing and having an opening in the side thereof communicating with said outlet port, a tubular valve fitted over said post, a spring normally closing said valve, and a rod connected to said valve and extending through said casing.

3. A device of the character described, including a casing having a restricted outlet port and a suitable inlet port connected to a source of fluid supplv. said outlet port having a post surrounding the same and extending into the casing, a tubular valve fitted over said post, springs normally closing said valve, guide rods for the same iixed to one of the Walls of the casing, and a rod connected to said valve and extending through said casing, said rod being guided in its movement by said guide rods and the casing.

` 4. A device of the character described, comprising a casing consisting of a cylindrical tube, having a top at one end and a bottom at the other, said bottom having an outlet port, a centering bell depending from said bottom and surrounding said port, a resilient Washer arranged within said bell, means for connecting said casing to a source of suitable fluid, a post extending upwardly from said bottom, a valve slidably mounted on said post and serving to close said outlet port, a valve stem protruding through said top to operate said valve, rods extending upwardly from said bottom, springs surrounding said rods, and a cross piece attached to said valve and pressed upwardly by said springs to normally close said valve.

1n Witness whereof, l have hereunto subscribed my name in the presence of two witnesses.
